Hi,

I was quite interested to see this in the changelog of the latest Quake3
point release:

- SMP support in the renderer. Detects CPU count, r_smp 1 default if
available. (thanks to Gareth Hughes for contributing this)

Starting up with +set r_smp 0 is still ok. However, when I start up
trying to use r_smp 1 quake3 exits (not very cleanly, but ok) it tells
me: 

mga_get_buffer_ioctl: flush ret=-22

bang. dead. It doesn't lock my computer, but mouse input etc doesn't
work till I restart X.

hardware is:
- 2x P3-800 on a BX chipset (not overclocked or anything - running
100mhz FSB)
- a matrox G550

software is:
- Debian with Xfree 4.2.1  (I tried both the matrox distributed drivers
and the Xfree ones.)
- Linux 2.4.19 SMP

One final note: since it is the default behaviour of quake3 to start
with r_smp 1 when >1 cpu's are detected, I'd expect it to break for
everyone using SMP and matrox. (maybe it even only works on nvidia?)

Thanks,

-- Mourad
